Abstract
We have fabricated a chip-level-integrated top-gate n MISFET with sputter-deposited-MoS2 film and confirmed n-type operation. A sputtering method enabled us to form a large-scale MoS2 thin film followed by H2S annealing to compensate sulfur vacancies. Two passivation films of ALD-Al2O3 enhanced the process endurance of MoS2 channel. Therefore, we realized TiN-top-gate n MISFETs and this process is a substantial first step to realize industrial chip-level LSIs with MoS2-channel FETs.
